Hi Senschu:
Yes, the book is still available from my website:
http://wwiijeepbook.com/
my email is:
jeepguy@rensjeep.com
Furthermore, the book is available from Ron Fitzpatrick jeep Parts (http://www.g503.com), Peter DeBella and other US jeep parts suppliers. I don't know of any UK booksellers who have the book at this time.
Thanks for your interest in the book and feel free to email me with any questions.
Cheers,
Ren Bernier
